This is an example of a contact us form, designed using HTML, CSS, and Bootstrap framework 4. The body of the form is given a background color of #ffffff, whereas the information card is given a style set of padding as 8%, padding-top as 35px, margin-top as 60px, and margin-bottom as 80px. The input text fields are given the styles of background-color as #616161, border-color as #616161, and font color as #BDBDBD. In a focus event, the input fields take the color of background-color as #000000, and font color as #BDBDBD. The border color of the fields also takes the background color as it inherits the color from the background. The email text field is given a height of 45px, whereas the message text field is given the height of 120px. The 'Submit' button is created as a Submit type button and given a background color of #5C6BC0, and font color of #ffffff. Source: https://bbbootstrap.com/snippets/contact-us-form-74769228
